About you
Your height is doing real work here. We use it to check the video's timing against gravity, which is how we catch a clip that's secretly running slow.
These get stored with every result. If any of them change, the app won't put the two sessions on the same line, because they wouldn't be comparable.
Hands on hips is the standard. An arm swing is worth 10 to 30%, so it's a different test, not a better score.
Step 2 of 3
Slow motion, 240 fps. The clip only needs the jump itself plus a second either side.
Nothing is uploaded. The file is read in your browser and stays there.
Step 3 of 3
Drag to the moment just before you leave the floor.
